Open End Pop Blind Rivets with Dome Head 2mm-6.4mm Steel Mandrel & Aluminium Blind Rivets Variety Sizes

Open end pop blind rivets with dome head, aluminum body and steel mandrel in various sizes from 2mm to 6.4mm. Reliable blind fastening solution for industrial assembly.

Open End Pop Blind Rivets with Dome Head

Open End Pop Blind Rivets are versatile blind fasteners designed for joining two or more materials when access is available from only one side of the assembly. Featuring an open-end construction, dome head, aluminum rivet body, and steel mandrel, these rivets provide a practical fastening solution for sheet metal fabrication, machinery, automotive components, construction, electrical enclosures, and general industrial assembly.

Blind rivets are also commonly known as pop rivets because they can be installed quickly with a compatible blind rivet tool. Unlike traditional solid rivets, which generally require access to both sides of the workpiece during installation, blind rivets can be installed from one accessible side.

This makes them particularly useful for enclosed structures, hollow profiles, panels, tubes, and assemblies where reaching the rear side is difficult or impossible.

Open End Blind Rivet Design

The open-end design allows the rivet mandrel to pass through the rivet body during installation. When the mandrel is pulled by the riveting tool, the rivet body deforms on the blind side of the workpiece and forms a mechanical joint.

The dome head provides a rounded head profile on the visible side of the assembly. This design offers a clean and commonly used appearance for general-purpose industrial fastening.

The actual joint performance depends on the rivet diameter, length, material combination, grip range, hole size, and installation method.

Aluminum Blind Rivets with Steel Mandrel

These pop blind rivets typically combine an aluminum rivet body with a steel mandrel.

Aluminum provides a lightweight rivet body and can be useful in applications where weight reduction and corrosion considerations are important. The steel mandrel provides the pulling element required during installation.

This material combination is widely used in general fastening applications involving sheet metal, aluminum components, panels, and other compatible materials.

When selecting rivets, manufacturers should consider galvanic compatibility between the rivet and the materials being joined, particularly in outdoor or humid environments.

Available Sizes from 2mm to 6.4mm

A variety of rivet diameters and lengths can be supplied to accommodate different fastening requirements. The requested range of 2mm to 6.4mm covers small and general-purpose blind rivet applications.

Rivet selection should not be based on diameter alone. The correct size also depends on the thickness of the materials being joined.

Important specifications include:

Rivet Diameter
Rivet Length
Grip Range
Head Diameter
Head Height
Rivet Body Material
Mandrel Material
Hole Diameter
Joint Material
Required Clamping Performance

Selecting the correct grip range helps ensure that the rivet can properly deform and create a secure joint.

How Pop Blind Rivets Work

Installation is relatively straightforward when using a suitable blind rivet tool.

A typical installation process includes:

Drill or prepare the correct hole.
Align the materials being joined.
Insert the blind rivet through the assembly.
Place the rivet mandrel into the riveting tool.
Activate the tool to pull the mandrel.
Allow the rivet body to expand on the blind side.
Break and remove the mandrel.
Inspect the finished joint.

The exact installation procedure depends on the rivet tool and application.

One-Side Installation

One of the primary advantages of blind rivets is their ability to be installed from one side.

This makes them suitable for structures such as:

Sheet Metal Panels
Enclosures
Tubular Components
Aluminum Profiles
HVAC Ductwork
Automotive Panels
Electrical Cabinets
Machinery Covers
Metal Frames
Equipment Housings

When the rear side of a workpiece is inaccessible, blind rivets can provide a convenient alternative to conventional through-bolting or two-sided riveting methods.

Dome Head Blind Rivets

Dome head blind rivets are widely used because the rounded head provides a conventional finished appearance while offering a practical fastening surface.

They can be used for applications where the rivet head remains exposed after installation. For specialized applications requiring a flush surface, other blind rivet head styles may be more appropriate.

Before purchasing, manufacturers should confirm the required head profile based on the assembly design and appearance requirements.

Industrial Applications

Open end aluminum pop rivets are used across a wide range of industries.

Typical applications include:

Sheet Metal Fabrication

Used for joining metal sheets, brackets, panels, and fabricated components.

Automotive Manufacturing

Suitable for selected vehicle panels, brackets, interior components, and non-critical assemblies.

HVAC

Used for ductwork, sheet metal panels, ventilation components, and equipment housings.

Electrical Equipment

Useful for electrical cabinets, control boxes, panels, and enclosures.

Machinery Manufacturing

Can be used for machine covers, guards, brackets, and lightweight structural components.

Construction

Suitable for compatible metal panels, profiles, flashing, and general fabrication.

Furniture and Fixtures

Can be used for metal furniture components and other lightweight assemblies.

Advantages of Aluminum Pop Rivets
Lightweight

Aluminum rivet bodies can help reduce the overall weight of an assembly.

Fast Installation

Blind rivets can be installed quickly using manual, pneumatic, or other compatible riveting tools.

One-Side Access

Installation does not require direct access to the rear side of the joint.

Versatile Sizes

Different diameters and lengths allow manufacturers to select rivets according to material thickness and joint requirements.

Clean Appearance

The dome head provides a smooth, rounded visible profile.

Suitable for High-Volume Assembly

Pop rivets are well suited to repetitive fastening operations in manufacturing environments.

Selecting the Correct Blind Rivet

Choosing the correct rivet is essential for reliable fastening.

Manufacturers should evaluate:

Total Material Thickness
Required Grip Range
Hole Diameter
Rivet Diameter
Rivet Length
Material Combination
Joint Strength Requirements
Environmental Conditions
Installation Tool

For example, selecting a rivet that is too short may prevent proper blind-side formation, while an excessively long rivet may produce unnecessary deformation.

For OEM production, testing the selected rivet on the actual materials is recommended before large-volume purchasing.

Quality and Manufacturing Consistency

For industrial buyers, consistent rivet dimensions and reliable mandrel performance are important considerations.

Quality control may include inspection of:

Rivet Body Diameter
Rivet Length
Head Dimensions
Mandrel Dimensions
Material Properties
Surface Finish
Grip Range
Pulling Performance
Finished Joint Appearance

Consistent manufacturing helps customers maintain predictable installation performance across production batches.
